DYEING MACHINE.

Specification of Letters Patent.

Application filed June 18, 1920. Serial No. 389,989.

cur, the dyeing is done unevenly and what are known as heat wrinkles are present in the work; loss being incurred, as many of the defects are not always noticeable until the dyed work is being pressed.

One of the salient features of the invention consists in the use of a paddle wheel formed and constructed in such manner that its blades strike the dye liquor in the tank [and which revents the carr in over ofv goods in th'e dye tub. The paddle wheel also prevents tearing and bunching of the garments, and permits the dye liquor to readily run off the paddles or blades, thus insuring superior action and operation.

Another feature consists in providing a series of conveniently disposed pipes for steam, hot water andcold water, so that any of them can be used separately or conjointly r at any. time.

The features and advantages of my invention will readily become apparent from the following specification and claims.

In the accompanying drawings, forming a part of this specification,

Fig. 1, is an isometric view of my machine,

Fig. 2, a top or plan view thereof,

Fig. 3, a section on the line is a section of the tub, partly broken away and of the gear, housing and guard.

Fig. 4, is an end view looking toward the paddle wheel, gearing and other parts, the housing or guard for the gears, being removed, and V Fig. 5, is a side view of the paddle wheel to show the contour and construction of its hub and paddles.

The dyeing tub is marked 1, and is usually oval in configuration, and in its center is placed an oval, hollow upright post or fixture 2, an oval path 3 being present between the post 2 and the wall of the tub 1, to form a route or passageway for the goods which are being dyed; the walls of the hollow post 2, provided with openings 4, whch pass therethrough; and as many of'these openings may be used as desired, a pipe 5 passes down into the hollow post 2 until it reaches the bottom 6, where it passes through the wall. forming said hollow post extending out to form a nozzle 7, providedwith holes 8. With the pipe 5 are connected, at its-upper extremity, the pipes 9, 10, 12, the pipe 10 maybe a continuation of the pipe 5, these pipes are eachgoverned by valve 13, each pipe having such a valve. I

One of these pipes is used for steam, another for hot water and the other for cold water, sothat any can be us'edwhen occasion re uires. v

n the shaft 14 in bearings 15 and 16, I mount and support a paddle wheel formed of a hexagon hub 17 provided with paddles or blades 18. A bracket 19 consists in holding up thebearing16. I further provide an upwardly extending bracket arm 20 having a supporting arm 21; In the bracket arm 20 at the base of which is the bearing 16 in which the shaft 14 is journaled, in' fact, it extends therethrough and the large gear 22 is fastened thereon, a smaller gear 23'which meshes withg'ear 22.,being placed on. shaft. 24, the tight and loose pulleys 25 and 26 being placed onthe same shaft 24.

I A shifter rod 27 is supported in arm support 24 and on long supporting arm 28; it is provided with 'fingers29 and 30 and the belt can be shifted to the right or left onto pulleys 25 or 26, as needed. The gears are covered by a guard 31.

The machine operates as follows: The dyeing liquor is placed in the tub or receptacle 1; the belt is shifted to a proper pulley and this revolves the shaft 24, thus revolving the small gear 23, which meshing with the large gear 22, revolves the shaft 14, which carries around the paddle wheel; blades of which strike the dyeing liquor at any desired point; the blades 18 of the paddle wheel striking the dyeing liquor forces it around the path 3, between the walls of the tub 1, and the hollow post 2; in the direction shown by the arrow in Fig. 1, the paddle wheel revolving in the direction shown by the arrow in Fig.

3. The dyeing liquor is thus kept in the state of agitation and in a revolving course over the path 3; the articles, clothes or other things to be dyed, also pass over this course carried along by the dyeing liquor and the V paddles 18 of the paddle wheel; hot or cold water or steam can be run int-0 the hollow post, through pipe 5 as desired, and it will pass out through the holes in pipe 7, in the same direction as thedyeing liquor is running; the hollow post 2, having a multiplicity of holes 4, to allow the proper circulation.

It will be noted that the hub 17 of the paddle wheel is hexagon in shape, so that the blades or paddles 18 thereof are placed on the hexagon sides of said hub, this enables the dyeing liquor to quickly pass off of the blades when said paddles, are in their upward course, and also enables any articles, clothes, fabrics or the like which have been caught up by the paddle wheel to quickly and readily fall off, back in the dyeing liquor preventing any tearing of the articles or clothes and preventing bunching; thus more thoroughly allowing the dyeing liquor to produce its proper and expected result in dyeing the clothes or the like.

The edges of the blades of the paddle wheel are usually rounded. I may make the hub and the blades of the paddle wheel of any other shape or contour, which will give the result desired by the use of my new wheel, and it may be revolved in any other desired manner.

It will readily be observed and apparent that by use of the dyeing machine made after my invention, a continuous uninterrupted and eflicient operation results, thus quickly and thoroughly dyeing the clothes or other articles operated upon, assuring high class dyeing and preventing variety or shape of color, producing uniformity of color and evenness of the work done.

What I claim as new and my invention and desire to secure by Letters Patent is:

1; A dyeing apparatus including a tank having an unobstructed annular chamber adapted to contain dye liquid, and a rotatable paddle wheel for circulating said liquid around. said chamber,said Wheel having blades disposed tangentially to the axis of rotation.

2. ri'dyeing apparatus including a vat having an endless unobstructed chamber therein designed to contain dye liquid, and a rotary paddle wheel for circulating the liquid around said chamber having'blades ar ranged tangentially to the axis of rotation of the paddle wheel.

3. A dyeing apparatus comprising a tank provided with an endless unobstructed chamber designed to contain dye liquid, a horizontally disposed shaft, and a paddle wheel mounted on said shaft and provided with paddles disposed tangentially to the axis of said shaft, said wheel extending into said chamber for circulating the liquid around said chamber. a 4:. A dyeing apparatus including a tank having an open top and provided with an endless chamber, a central chamber arranged within the other chamber, a supply pipe extending through the central chamber and having an angular extension projecting into the endless chamber and provided with apertures arranged at one of its sides and a paddle wheel for circulating the dye liquor around said endless'chamber,

5. A dyeing apparatus including a tank provided with an endless unobstructed chamber designed to contain dye liquid, a horizontal shaft, a hub mounted on said shaft and having a hexagonal periphery, and paddles fixed to the faces of the hexagonal periphery and arranged tangentially to the axis of-said shaft for circulating the dye liquor in v the tank.

I In testimony whereof, I aflix my signature at Cincinnati, Ohio, this 15th day of June, 1920.

ADAM W. SEHN.
